Notes: 1. The output transistor has an open collector structure.
Notes: 2. The status of the external trigger input is as follows:
Notes:
This is a sample circuit for driving an MA Motion Sensor. Noise protection was not
taken into consideration.
To increase reliability and protect against noise, add a noise filter to the input. In
addition, add a circuit that accepts the output in synchronization with the start sig-
nal and issues a detection signal when the same output is repeated several times
in succession.
Please note that we bear no responsibility for any damages or loss arising from the
use of this circuit.
I need to design pulse generating circuit
using the external trigger type. Could you
show an example drive circuit?

Detection status: Output transistor ON (connected to GND)
Non-detection status: Output transistor OFF (open state)
Open at the high level
GND (less than 0.8V) at the low level
Under no circumstances must a high-level voltage be applied.
